Gyros

[EROCK]

Hey everyone when we received our kit of parts, it was missing the sensor strip (gear tooth, yaw rate gyro, dual axis accelerometer). We were wondering if anyone knew where we could obtain these boards.

If you were missing parts, you should've contacted FIRST by January 9 (10.1.1).

As for the actual parts, you'll have to settle for buying similar ones; the official sensors have never been available elsewhere.

well what are people using the Gyros for? do we really need them? I have just found out that we had them but they were inadvertently broken. Is there any place where we could purchase a comparable gyros board?
Any input would be helpful...
Thanks

What are you planning on using the gyro for? Going to any major electronics provider you can get an Analog Devices evaluation board (the kit gyro is pretty similar to an ADXRS150EB).

We've always found the kit gyro a little turn-rate limited, so we've always used an ADXRS300EB, which can handle faster turn rates.

We are also missing the gear tooth sensor and the dual axis accelerometer. Do you know where we could find these?

I don't off the top of my head.

(I think we have unused ones from previous KOPs. I'll check our inventory, and if so I'll PM you).

He thanks so much for the help. We really appreciate it. If you need any other info just message me.

Haven't found it yet. I'll have the students look some more tomorrow.

Have you contacted FIRST yet? There's a good chance they'll send another sensor strip to you.

(Where in Minneapolis are you? I'm a former Minnesotan myself)

The gear tooth sensor is a basic hall effect sensor which can sense each tooth of a sprocket/gear in order to measure speed or distance traveled. You could get one of these from sparkfun.com, or you could use a different method of measuring wheel rotation, such as an encoder, which in my opinion are a little easier to use.

See Kevin Watson's page on encoders: http://www.kevin.org/frc/encoder/

Our actual team is from St. Paul but I live by lake nokomis in Minneapolis, and I shall contact first to see if they will send us a new sensor strip.

We have the GTS, but can't find a spare DAA or Gyro at the moment. PM me if you want me to send the GTS's.
